Abstract

Des résines de roto-moulage à traitement facile qui ont un indice de fluidité, I2, élevé (mesuré selon la norme ASTM D 1238), de 2 à 10 (en particulier de 3 à 8) grammes/10 minutes, et une distribution de masse moléculaire, Mw/Mn, étroite, de 2,0 à 3,0, sont difficiles à stabiliser avec des ensembles additifs correctionnels. La présente invention résout ce problème par lutilisation de 500 à 5 000 parties par million en poids (ppm) doxyde de zinc, en plus dun ensemble additif stabilisateur standard.
